On Monday, three London teenagers were arrested in Turkey for
allegedly attempting the journey. The male suspects from London –
two aged 17 and one 19 – were also arrested on suspicion of
preparation of terrorist acts.

They have been released on bail from a police station in the
capital.

Last month, three British schoolgirls from London traveled to
Turkey and are now believed to have crossed into Islamic
State-held territory. Shamima Begum, 15, Kadiza Sultana, 16, and
Amira Abase, 15, were captured on CCTV boarding a bus to the
Syrian border from Istanbul.

On Wednesday, a court placed a travel ban on a 16-year-old boy
because of concerns he may follow in the footsteps of his two
older brothers, who traveled to Syria and have since been killed
in the fighting.

In an interview earlier this week, Prime Minister David Cameron
highlighted his concerns over the number of boys and girls
attempting to travel to the region.

He told the BBC: “In the past the danger has been more about
boys but we can now see that is changing.”

“We can't entirely say it's a matter for the police or the
border force, everyone has to be involved in spotting signs of
radicalization and combating those signs.”

“It is a really big issue for our whole country to get to
grips with and work out how we put a stop to it.”
